SPREEN, OF DETROIT, MICHIGAN, ASSIGNOR TO KELVINATOR CORPORA- TION, OF DETROIT, MICHIGAN, A CORPORATION OF MICHIGAN CONDENSER FOR REFRIGERATING APPARATUS Application filed June 4, 1927. Serial No. 196,409.

Fig. 1 is a plan view of refrigerating ap-.

paratus with which my invention is incorporated; and

Fig. 2 is a front elevation of the same. Referring now to thedrawings by characters of reference, 10 represents a movable support upon which refrigerating apparatus is mounted. A compressor 16-and an electric motor 17 are mounted in spaced relation adj acent one side of the support and power is transmitted from the motor to the compressor by a drive belt 18. The belt extends around the motor pulley 11 and the compressor fan pulley 26. so The condenser unit extends in a vertical plane and is mounted upon the support 10 parallel with the drive belt so that the major portion thereof will lie in the path of air circulated by the compressor fan pulley 26. The condenser comprises a manifold section 13, preferably L shaped in construction, and a plurality of angularly bent tube sections 24 having one end secured to the upright ortion of the manifold and the other en secured to the base portion of the manifold. The tube sections and the manifold are arranged in open communication, and the tubes can be provided with projecting fins to increasethe heat transfer capacity of the condenser. .The legs of the tube sections are of different lengths so that the sections can extend in a single plane in spaced relation.

A conduit 20 extends from the outlet connection 19 of the compressor to the inlet conmotion 21 which is attached to the inlet chamtherethrough.

ber 12 which is secured upon the top of the condenser manifold, and conducts gaseous refrigerant from the compressor to the condenser manifold. A tube 14 is secured'to extend internally of the upright portion of the condenser manifold for conducting liquid refrigerant from the base of the manifold to the outlet connection 22 with which the conduit 28 is secured, the conduit 23 extending to the evaporator (not shown). The tube 14 is open at its lower end and is restricted at 1ts upper end and a manually adjustable valve 9 is associated with such restricted por-' t1on to control the liquid refrigerant passing 0s The compressed refrigerant will pass into the upright portion of the manifold'and will travel into the open ends of the condenser tube sectlons connected therewith and when condensed, in either the tube sections or the upright portion of the manifold, will fall by gravity to base portion of the condenser which serves as a reservoir. The base of the condenser is preferably of such capacity that the condensed refrigerant will not occupy the upper portion thereof, so that uncondensed refrigeranuwill be free to travel therein and through the tube sections in substantially a circular direction until condensed. The outlet tube 14 is arranged to permit withdrawal of liquid refrigerant through the upright portion of the manifold without interfering with the circulation of the gaseous refrigerant. The tube 14 further insures that substantially no gaseous refrigerant will pass from the con" 85 denser as the open end of the tube extends in a plane below the level'of the liquid refrigergnltdin the base portion of the condenser mani- Various changes can be made in the details of the condenser structure described without departing from the spirit of my invention and the scope of what is claimed.

\Vhat I claim is:

1. A condenser, for refrigerating appara- 9 tus, comprising a manifold having a base portion and an upstanding portion, tube sections extending intermediate said manifold portions, and an outlet conduit extending into said upstanding manifold portion.

2. A condenser, for refrigerating apparatus, comprising a manifold having a base rtion and an upstanding portion, tube sections extending intermediate said manifold portions, and means associated with the top of said upstanding manifold portion for conveying refrigerant to and from said manifold.

3. A condenser, for refri erating apparatus, comprising a manifol having an upstandin portion, tube sections extending from said manifold, and a valved connection secured to the top of the upstanding portion of said manifold for controlling the passage of refrigerant into and from said manifold.

4. A condenser, for refrigerating apparatus, comprising a manifold having an upstanding portlon, tube sections extending from said manifold, and an outlet tube extending into the upstanding ortion of said manifold, the end of said out at tube within said manifold being arranged adjacent the bottom portion of said manifold.

In testimony whereof I hereunto affix my signature.
